Datasheet Q6012LTH1LED (Littelfuse)

Teccor® brand Thyristors
12 Amp Alternistor Quadrac for LED dimmer applications Q6012LTH1LED Series RoHS
Description
The Quadrac is an internally triggered Triac designed for AC switching and phase control applications. It is a Triac and DIAC in a single package, which saves user expense by eliminating the need for separate Triac and DIAC components. Q6012LTH1LED series is designed to meet low load current characteristics typical in LED lighting applications. By keeping holding current at 8mA maximum, this Quadrac series is characterized and specified to perform best with LED loads. The Q6012LTH1LED series is best suited for LED dimming controls to obtain the lowest levels of light output with a minimum probability of flickering.
Agency Approval
Q6012LTH1LED series is offered in the industry standard TO-220AB package with an isolated mounting tab that Agency Agency File Number makes it best suited for adding an external heat sink. L Package : E71639
